MATTRESS-FRAME.

Specification of Letters Patent.

Patented A11 10, 1915.

Application filed February 24, 1913. Serial No. 750,057.

To all whom it may concern Be it known that 1, Or'ro GAsAU, a citizen of the UnitedStates, residing at i3roo'klyn, in the county ofKin-gs and'Sta-te of New York, have invented certain new and useful Improvements in Mattress-Frames, of which 7 the following is a specification.

This invention has to do with spring or mattress frames, it moreparticularly relat- 7. ing to the corner brackets thereof by means of which the frames are supported upon the frame or side bars of the bedstead, the ob ject of the invention being to provide an improved corner bracket or supporting means for "the spring ora nattress frame which is capable of adjustment so as to. enable the spring or mattress frame to be used with varying widths of'bed frames and which 'isalso eifective to interlock the mate tress frame with the bed frame. 7 I

A further object of the invention isthe provision ofa-n improved-mattress frame attachment in the form of a corner bracket which is simple in its construction, effective in use and inexpensive to manufacture, and

by the use of which the mattress frame may fit varying widths'of bed frames and be so interlocked therewith that movement of the mattress frame lengthwiseof the bed frame is prevented. I

It is well known in practice that the bedstead frames of variousmanufacturers differ in width, and it is also well known that weather conditions have considerable to do with varyingthe width of the metallic bed frames, so that it is'desirable that the mattress frame shall have "shif-table or adjustable means whereby it will fit within reasonable limits the varying sizes of bed frames.

It is also well known that mattress frames or spring mattresses warp in transportation as well as in use, so that when applied to the bed frame they frequently rock by reason of the fact that one :or more of the corners do not rest upon the side bars as they should. By reason of the present improvement, however, this rocking of the mattress frame is avoidedbecausethe mattress frame will be interlocked and clamped at all four corners on the side bars, so that each corner will equally bear upon its side bar andbe prevented from rising above.

consequent annoyance and rattle of the j'usted position.

the side bar by warpage or other reasons, and thus any rocking movement of the mattress and the spring mattress when being sat or slept' upon is entirely avoided.

The present invention is therefore an improvement in part upon my prior Patent No. 1,085,571, dated August 13,1912.

in the drawings accompanying and forming part of this specification, Figure 1 is a perspective view of a bedstead and spring or mattress frame supported thereon; Fig. 2 is a detail view of one of these improved corner brackets; Fig. 3 is a detail view of a somewhat modified form thereof; and Fig. i

is a detail view of the adjustablermember carried by the bracket.

Similar characters of reference indicate corresponding parts in the di 'fierent figures of the drawings.

The mattress frame 2 comprises usually a pair of transverse or crosswise extending members or anglebars 3 for supporting .a

suitable spring fabric 16 under tension connected-to what is known as corner brackets 4:, which corner brackets are usually formed to receive side bars 5. In the present instance each of these corner brackets is provided with a guideway 6 extendingtransverse'ly' of the bracket at the end :of the socket portion 7 which receives the :end of the side bar, this guideway being in the form of a casing closed on all four of its sides but open at its ends. In this guideway casing is located the adjustable member, which consists of an adjustable slotted bar 8 through theslot of which a bolt projects having a threaded end for the reception of a nut 9 adapted to fit in an angular opening 10 of the guideway casing and a wingnut 11 on the end. By clamping the wing nut.

tightly the adjustable bar is held in its ad- The end of this bar is formed with a projecting recessed portion 12'forming an overlapping projecting portion 13 and an underlapping projecting portion 14 shorter than the overlapping portion, the projecting overlapping portion 13 being adapted to rest on the top of the side bar of the bedstead and the underlapping I portion adapted to extend under the edge of the same, whereby the edge of the side bar will be received within the recess of this adjustable member so that when the locking nuts are clamped the mattress frame will be held againstmovementby reason of the reception of the side bar within the recessed end of each adjustable member. By adjusting the adjustable members to tightly eni mattress'frame from ofii the bedstead frame is alsoprevented until the side bars are re- 7 leased from the adjustable members.

The adjustable sliding bars or members gage the side barsiii the manner described movement of the mattress frameleng'thwise or crosswiseof the bedstead will be prevented in a manner which will be readily understood. Moreover, by reason of the interlocking of the adjustable members of the corner brackets with the sidebars the lifting of the areso formed that they may be readily reversed if this should be necessary for any purpose; that is to say, they are interchangeable lone with another. In the-form shown in Fig. 3- the adjustable interlocking member or bar of the bracket is shown located below a laterally projecting member 15, which-may be used to support the mattress frame at each corner on the side rail or bar of the bedstead if for any purpose it IS desired to remove the adjustable bar; In other words, by removing the adjustable bar the forward end of which is located under the side extension ofthe bracket, each bracket may be used in the ordinary manner for supporting the mattress frame at its cor- V ners. upon the side rails. s It will be'observed' that thecorner brackets are so formed that engage the side rail ofa bedstead.

Copies of this patent may be obtained for .for clamping said bar 3; A mattress frame having corner brackets each provided with a lateral extension formed to rest upon the side rail of a bed stead and having below said extension an adjustable slidable'locking bar adapted to engagethe side rail of a bedstead, and means i in any of its adjusted positions.

4. A mattress frame having corner brackets each provided with a lateral extension :formed torest upon the siderail of a bed-o stead and havlng'below said extension an adjustable slidable locking bar adapted, to engage the side rail of a bedstead, and means for clamping said bar in any 01 its adjusted positions, said bar havingvits end formed to interlock with said S]Cl6 rail. i 5. A mattress frame having corner brackets each provided with a lateral extension formed to rest upon the side rail of a bedstead and havingbelow said extension an ad ustable shdable lockmg bar adapted to engage the side rail or" a bedstead,,and

adjusted positions, said bar 'havingits end provided wlth a pair of pro ections. adapted to overlap and underlap the side rail and forming a recess for the reception of said side rail.

6. A riser corner bracket for a mattress frame having a closed guldeway casmg'except at its ends, a slotted adjustable slidable locking bar therein, and means for clamping said bar in said casing, said bar having means at its end for interlocking it with the side-rail of a bedstead." i Y Y Signed at New York, in the county of Queens, N.
